This paper reports on a search for narrow resonances in diboson production in the ââqq¯ final state using pp collision data corresponding to an integrated luminosity of 20  fb -1 collected at s=8  TeV with the ATLAS detector at the Large Hadron Collider. No significant excess of data events over the Standard Model expectation is observed. Upper limits at the 95 % confidence level are set on the production cross section times branching ratio for KaluzaâKlein gravitons predicted by the RandallâSundrum model and for Extended Gauge Model Wâ² bosons. These results lead to the exclusion of mass values below 740 and 1590 GeV for the graviton and Wâ² boson respectively.
